This iridium compound is easy to make, stable in air, and works better for hyperpolarization than the more complicated carbene-based catalysts usually used for this purpose.
Scientific Claim
The iridium complex [IrCl(COE)2]2 serves as a simple and readily available air-stable precursor for SABRE hyperpolarization, with better performance than carbene-based complexes typically used for this process.

More Accurate Statement
“The iridium complex [IrCl(COE)2]2 is associated with serving as a simple and readily available air-stable precursor for SABRE hyperpolarization, with better performance than carbene-based complexes typically used for this process.”
Source Excerpt
“In summary we have established that readily available air-stable 1 reacts with py and H2 to form 2. 2 is highly effective for hyperpolarization of py via the SABRE effect in nonprotoic solvents and with its simple alkene coligand far easier to employ than the carbene complexes more usually used.”
